Tonga volcano unlikely to erupt again for decades - volcanologist

Sunday will mark one year since the Hunga Tonga-Hunga Ha'apai eruption. 

Marco Brenna, a volcanologist at Otago University, ​says the volcano is still technically active, but it’s very minor. 

“The volcano is still brewing away, although deep beneath the waves, but a lot of that energy that had been stored has been lost, so it’s unlikely that the volcano will produce such a large eruption again in the next few years, decades even.”

The most recent eruption followed previous patterns to begin with, says Brenna.
